    It looks to me that the creator added a gradient layer over the model and set the blending mode to "multiply"

    The right way is to learn to control your lighting. All they did was place a flash behind the model and place a pink gel over the light... then blasted away at the background blowing out the center and fading out. :)

    Medium grey background with a red gel over it.

    Same medium grey background with a blue gel over my flash.

    Make sense?

    Makes total sense, but how do you get the white center with the color?

    I tried using the circle gradient tool on a colored background, but cant get the blending of white to color to look clean even with feathering...you can still see the hard outline of the circle.

    Increase flash power. It doesn't matter what colour gel is on it... if it is high enough it will ALWAYS be white.

    ... plus some "dodging" of the gradient layer (probably painting on a Layer Mask) around the face and hair to avoid the ugly tinting that can be seen on the feet and shoes.

    The classic studio lighting method mentioned, and well illustrated with some very nice examples, by JerryPH will generally yield much more real looking results. No false halo around the head, like that seen in the OP's link. Getting a clean white center with this method does require some substantial flash units. The background light needs to be substantially brighter than those on the subject.

    The one you posted was done with PP as a couple of people have mentioned.

    They outlined the person with the pen tool (maybe layer mask, millions of ways to do this) then they adjusted the gradient so that the white lasted longer before being mixed with the other color.

    It was a somewhat poor job though, for some reason her feet are behind the gradient? Yet her head is in front of it? Maybe that was the point, I'm not one to judge!

    Still, as Jerry noted, the best way is just to learn to control your light. For the original shot, I suspect having the light behind a translucent material and shooting through that as the background toward the camera would produce better results. Ah well...

    I do agree it is better to do lighting ahead of time, but personally I like to have the option of having my model against a pure white background so I can adjust the background at a later time if needed :)

    This gives you the chance to have a lot more flexibility with older photos that you may want to re-purpose later on. Pen tool the figure once, have a model with no background for life!

    I tend to look at things from a "How can I save my butt later if something goes wrong" - kind of light. If the client decides that instead of all those blue backgrounds we shot, they would much rather a nice yellow. Well I already have the cut out done, so I just have to adjust my colors.

    There is no wrong way to achieve this, as always the question is what is your end goal?

    Hehe I don't mean to skewer anyone :X

    It is one of those - because we're able to - moments. Would I do that for every shot? Most of em, but in the end if I know what I want I have no reason to bother with PP.

    It looks so much more natural when you just set the lights up properly.

    I totally see the point with setting up the lights.

    However, I am going for the model forever technique....cut out my subject and put them on different backgrounds. I wanted to use this technique for some pinup style work.

    Even then, I need to light my subect right to make her fit in properly.

    touche to both sides! :hugs:
